The season premiere of 'Arrow' Season Four has come and gone, but fans still can't stop talking about that scene where Oliver Queen (Stephen Amell) and Barry Allen (Grant Gustin) are seen standing in front of a recently covered grave. Although it may still take a few more episodes before the truth is revealed, even the stars of the show can't help but wonder who would possibly get killed off.

So who could possibly get axed in the fourth season of 'Arrow?'

A popular speculation suggests that it could be Oliver's new love interest Felicity Smoak. After all, even Stephen Amell has considered the possibility, telling TVLine, "You can kill off anyone. Modern television has proven to us that you can literally kill off anyone."

Emily Bett Rickards, who plays Felicity in the series, admits that the cast worries about it and she has even theorized it could be her character.

"As castmates, we're all like, 'Is it you?! Is it you?! Oh, it could be you!" she said. "'No, you know what, it's definitely me. It has to be me! It's has to be you! It has to be me! It's going to be them! It's going to be no one! No one's in the grave!' Like, that conversation happens daily."

Another actor who is also wondering if it is his time to go is Paul Blackthorne, who plays Captain Quentin Lance. However, Blackthorne seems to be more open to the possibility.

"I'm just thinking, 'That's four years in. Can't complain, I'm very happy,'" he admitted. "If you're propping up the daisies at the end of it, then so be it."

But not too soon, Paul Blackthorne hopes. "It'd be nice to keep going," he said. "It's a nice show to work on."
